I would simply create a reusable UIViewcomponent and everything you need as a subview, such as a UIImageViewfor your image, a UILabelor a UIButtonin the top right. Here is the process to show it:

我会简单地创建一个可重用的UIView组件和您需要的所有内容作为子视图，例如UIImageView您的图像的UILabela UIButton，右上角的a或 a 。这是显示它的过程：

1. Create a UIViewthat takes up the full screen, make it black, and maybe 0.5 alpha.
2. Create another UIViewwhich is your primary pop-up view, make it slightly smaller than the previous view, but make sure both of these views are subviews of the parent subview.
3. Add the desired elements on to the pop-up view as subviews, I would even suggest creating a UIViewsubclass if you plan to use this a lot.
4. To present the pop-up, make sure both views are set to hidden = truewhen created and so that when a button is selected, you can set them to hidden = false
5. If you would like them to be animated, simply start them off with alpha = 0.0and use something like UIView's animateWithDurationand set the pop-up view to alpha = 1.0

1. 创建一个UIView占据全屏，使其变黑，可能还有 0.5 alpha。
2. 创建另一个UIView作为主要弹出视图的视图，使其比前一个视图略小，但要确保这两个视图都是父子视图的子视图。
3. 将所需元素作为子视图添加到弹出视图中，UIView如果您打算大量使用它，我什至建议创建一个子类。
4. 要显示弹出窗口，请确保hidden = true在创建时将两个视图都设置为，以便在选择按钮时将它们设置为hidden = false
5. 如果您希望它们具有动画效果，只需启动它们alpha = 0.0并使用类似 UIView 的东西animateWithDuration并将弹出视图设置为alpha = 1.0

There is a lot of little details you can change to cater to your needs, but this is the basic structure on how to accomplish your goal.

您可以更改许多小细节以满足您的需求，但这是实现目标的基本结构。
